The gold standard in mattress protection Your sleep is precious, so keep your mattress & pillows in the best possible condition. This incredible protector encases your entire mattress or pillow, leaving it waterproof & completely protected against the nasties that can make you unwell. Dust mites, pollen, pet hair, & mould spores won't stand a chance; your mattress & pillow will be as pristine as the day you bought them. It's also a worthwhile investment for anyone living in rented accommodation, sleeping on a mattress which has been previously used. Adjustable for standard & thicker depth mattresses. Please note this range is spill proof & not suitable for bed wetting. For total waterproof protection try our Washable Absorbent waterproof mattress pad.
